Snow falls in the Earth's extreme North and South throughout the year. However, the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道), but only on the highest mountains.

    Snow contains much less water than rain, but much of the water the world uses comes from snow. {#blank#}1{#/blank#} In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.

    Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. {#blank#}2{#/blank#} The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow's surface will help to send back sound waves.

    {#blank#}3{#/blank#} It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. {#blank#}4{#/blank#}.

    People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. {#blank#}5{#/blank#}

A. These include food, emergency medical supplies, and extra clothing to stay warm and dry.

B. Snow also influences the movement of sound waves.

C. Melting snow provides water for rivers, electric power stations and agricultural crops.

D. Mountain snowfall is heavier than that in the South and the North Poles.

E. In many places, streets were blocked; houses fell down and supplies were short.

F. Others die from heart attacks caused by too much physical activity out in the cold.

G. Snow may be beautiful, but it can be deadly.

The Winner's Guide to Success

    Do you know what makes people successful? To find out the answers, an American reporter recently visited some of the most successful people around the world.{#blank#}1{#/blank#}

Be responsible for yourself

    Sometimes you may want to blame others for your failure to get ahead. In fact, when you say someone or something outside of yourself is stopping you from making success, you're giving away your own power.{#blank#}2{#/blank#}

Write a plan.

    It's very difficult to try to get what you want without a good plan. It's just like trying to drive through strange roads to a city far away.{#blank#}3{#/blank#} Without this “map”, you may waste your time, money and also your energy; while with the “map”, you will enjoy the “trip” and get what you want in the shortest possible time.

{#blank#}4{#/blank#}

Nothing great is easy to get. So you must be ready to work hard—even harder than you have ever done. If you are not willing to pay the price, you won't get anything valuable.

Never give up.

    {#blank#}5{#/blank#}When you are doing something, you must tell yourself again and again: Giving up is worse than failure because failure can be the mother of success, but giving up means the death of hope.

A. A good plan is like a map to you.

B. It seems to us that everyone knows this, but it is easier said than done.

C. Some people achieve success much later in life because they don't work hard earlier.

D. You're saying, "You have more control over my life than I do."

E. Someone else's opinions of you don't have to become your reality.

F. Be willing to pay the price.

G. Here are some keys to success that they give.

    Each year, we are exposed to ten thousand ads on average. They try to sell us their products by using beautiful art, videos, images or slogans that are catchy. The most famous companies have highly popular logos that can be recognized by almost everybody. For those of you who have seen the movie Finding Forrester, there is that scene where Jamal walks up to some guy with a BMW and asks him what the car logo means. The man did not know the answer and since that day, whenever I see a famous company logo I try to find the meaning of it.

    Many think the horse on the Ferrari logo represents the horsepower of the cars they manufacture. The story behind it is far more interesting. During World War I, a pilot, Count Francesco Baracca, painted the horse on his airplane to bring him luck. He had it on his plane because it was the logo of his squadron（空军中队）. Baracca's mother then convinced Enzo Ferrari to put the logo on his racing cars in the early 1930's to bring good luck to the drivers. The logo then stayed the same ever since. The yellow on the background represents the birthplace of Enzo Ferrari.

    Starbucks started in 1971, in Seattle. The mermaid（美人鱼）represented on the logo is now known by any coffee drinker. It is a mythological sea creature with the look of a female, the only difference being that they have a tail of a fish. The reason why Starbucks incorporated one in their company logo is that it was believed that mermaids used to sing to sailors in order to make them walk away from their ship or to ground their ships. In the 1500s, spices, tea and coffee were popular merchandise to trade. So the mermaid in the logo of Starbucks is the one that "brings" coffee and tea to the stores.

    Our series The Genius Behind will take you inside the minds of people who are making the impossible possible. Whether it is designing the fastest ever land vehicle, helping the blind to see or creating space history, success relies levels of knowledge to new heights . What can we learn about genius from minds? Based on the people and the projects outlined in the series, we've come up with five lessons.

    Lesson one: New challenges require new ways of thinking

    Bloodhound SSC aims to be the first vehicle to break the 1,000 mph barrier. One of the key challenge has been to design the wheels. Thinking twice, Mark Chapman, chief engineer decided to change the way they were trying to solve problems and came up with a wheel design, part car, part jet fighter and part spaceship, which would hold together and was strong enough.

    Lesson two: Let evidence share your opinion

    Geophysicists widely believed that water on Earth originated from comets. But by studying rocks, Steven Jacobsen discovered water hidden inside, suggesting that the oceans gradually made its way out of the planet's interior many centuries ago. “Unfortunately, I had a pretty hard time convincing others,” he admits. Only time can tell whether the new theories are true.

Lesson three: It really is 99% efforts

    Sheila Nirenberg at Cornell University is trying to develop a new prosthetic device(假肢器官)for treating blindness. “Sometimes I'm exhausted and I get burnt out,” she adds. “But then I get an email from somebody saying that they can't see their own children's faces, and it is like, 'How can I possibly complain? Once I thought of this, I couldn't eat, I couldn't sleep—all I wanted to do was work'. It gives me the energy to just go back and keep doing it.”

    Lesson four: The answer isn't always what you expect

    Sylvia Earle has spent decades trying to see the ocean with new eyes. Her “dream machine” is a submarine that could take scientists all the way to the bottom of the deepest ocean floor what sort of material could best withstand the types of pressure y would encounter thousands of miles below the ocean surface?” It could be steel, it could be titanium, it could be some sort of ceramic, or some kind of aluminium system,” says Earle. “But glass is the best choice.”

    Lesson five: A little luck goes a long way

    It was considered as one of the biggest success stories in the history of space exploration—20 years of planning ended earlier this year with the Philae lander landing safely Comet 67P over 300 million miles(480 million kilometers)away from Earth, though Philae's anchoring harpoons(锚定鱼叉)didn't fire as planned.

    As a matter of fact, genius is difficult to define. “Genius is a funny word,” says Nirenberg. “I just sort of ignore it and just go on with life. You just do what you do regardless of whatever label's attached to you. I don't know really how else to explain it.

    The United States Postal Service(LISPS)is offering a way to people who are interested in seeing tomorrow's mail today. The postal service will send consumers images(图像)of their letters, magazines and other mail before they arrive. The new service is called Informed Delivery. It is an attempt to remain competitive in an ever—changing world.

    Postal service officials say the increased use of email, digital messaging services and social media has made it difficult to stay relevant. David Rupert is a media relations specialist who spoke about the competition the agency now faces. Whether you turn on a television or your computer, or people come to your door with different products and services, all of those are competing for consumers' time and energy, he said.

    Interested users are first required to sign up for Informed Delivery. Once registered, the consumer receives a daily email with virtual(虚拟)images of letters or other things to be delivered. The US Postal Service says it can especially help those who have a mailbox at their local post office, so they know when to get their mail：

    Another postal offering is a service that seeks to make advertising-related mail-often called junk mail—more fun. The service uses virtual and augmented reality(虚拟现实和增强现实)to let consumers interact with their junk mail. Many companies put special coding on their advertising, which can give users an interactive experience. Some companies even put virtual reality eyeglasses in the mail to make their ads come to life. Consumers have mixed reactions to virtual and augmented reality advertising. “You can find some good things within junk mail. It is a good idea. We'll see how it works, ”Postal service user Victor Teah said. But Jocelyn Coatney doesn't think it would change her mind about junk mail. “For some, that might be fun. But for me, it would be useless, ”she said.

Every profession or trade, every art, and every science has its technical vocabulary, the function of which is partly to name things, or processes which have no names in ordinary English, and partly to secure greater exactness in terminology (术语). Such special dialects are necessary in technical discussion of any kind. Being universally understood by those engaged or interested in the particular science or art, they have the accurateness of a mathematical formula (公式）. Besides，they save time in these kinds of discussions, for it is much more economical to name a process than to describe it. Thousands of these technical terms are very properly included in every large dictionary, yet, as a whole, they are rather in the suburbs of the English language.

Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other professions, like farming and fishery, which have occupied great numbers of men from remote times, the technical vocabulary is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very central part of our language. Thus, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technical terms. In law, medicine, and philosophy, the special dialects have also become pretty familiar to cultivated persons and have contributed much to the popular vocabulary. Yet among these professions, each one still possesses a large body of technical terms that remain essentially foreign, even to educated speech. And the proportion has increased in the last fifty years, particularly in the various departments of natural and political science and in the mechanic arts. Here new terms are coined with the greatest freedom, and abandoned when they have served their turn. Most of the newly-invented terms are restricted to special discussions, and seldom get into general literature or conversation.

Yet no profession is nowadays, as all professions once were, a close combination. Lawyers, doctors and men of science all communicate freely with others, not in a merely professional way. Furthermore, what is called "popular science" makes everybody familiar with modem views and recent discoveries. Any important experiment, though made in a remote or provincial laboratory, is at once reported online, and everybody is soon talking about it-as in the case of AI.
